"Insane Train" by Sheldon Russell -- A Wild Read

I enjoyed the ride!  Insane Train by Sheldon Russell tells the story of a detective named Hook, whose job it is to safe guard a train of patients from an insane asylum to Oklahoma.  As you can imagine, not everything goes as planned.  This is a fun mystery that will keep you guessing who the killer is.  I enjoyed it.  I give it 7 stars.  Did you see my teaser for this one?
